Attached is a door/window virtual device that is opened/closed based on ping responses. I wrote this for a specific scenario of mine: I have an A/V receiver and a dedicated external amplifier that I built. When building the AMP I never built a 12v trigger. Anyways, got tired of switching it on and off. Now, when my AMP comes on, it responds to pings which in turn sets the device as open and results in a z-wave switch being turned on.
